USING THE M-TUBE TO ITS WITHOUT FULLEST POTENTIAL

In order to utilize the full capacity of this unit$ is suggested that you

read this section from beginning to End and then if you still have

questions,our Tech assist department personnel can help.

The M-TUBE is a very unique device. Not only does it provide you

with extended range audio,faithfully preserving and reproducing all of

the original detail

nuances but it also has some pretty unique

features.With this device,you have the ability to either[a] maintain

separate

FRONT[Line] and REAR [aux] inputs and outputs or[b]

utilize either of the line /aux.inputs,to obtain outputs on both Front

Rear plus Sub,with full fader control.Please see the expanded

functional descriptions below.

Using the line input only

[place linelaux switch in

position1,the following is realized -there would be no output on the

Rear channels but there would be outputs on both Front

Sub

sections. At this time the input

select

switch is in the

IN"

position,moving this switch to the out position,will produce an output

on the Rear channels as

well.The fader control functions in favour of

"F"

or Front.

Using the Auxiliary input only

;

the following is realized-there would be no output

on the Front channels but there would be outputs on the Rear

Sub

sections. At this time, the

moving this switch to the out position, will cause ALL outputs

turned-off,

there'd be no output whatsoever on any channels. The

but there's no

USING THE M-TUBE TO ITS WITHOUT FULLEST POTENTIAL

Using two sets of inputs on both line and auxiliary

[the linelaux

switch can be either in or out],the following is realized-the program

material [music or other audio] presented on the aux. input will be

available on the Rear

Sub channels, while the materials presented

to the line inputs will be available on the Front channels exclusively. At

thistime, both switches line

aux are in the "IN" position, if the

select" switch [only] is now placed in the

OUT" position, the

line- input channels' program material, will now be available on ALL

outputs

thereby effectively switching off or canceling the aux. inputs.

The fader control functions to

balance" between line or

and auxiliary or

"R"

What are the benefits of the above features you may ask: Well, for the

first time, you can incorporate a preamplifier to enhance the entire

system but still maintain

separation between the Front channels and

the Rear channels

if this is your preference. That way, you can add

pre or post equalization and or crossover functions to either Front

and/or Rear without affecting the other! This is just one example, the

only limit here is your

imagination..note that while equalization can be

added pre or post the preamplifier's processing we suggest that

crossover functions be added after or post preamplifier processing.

FEATURES

The subwoofer output is an additional convenience when you

wish to add subwoofers to your audio system to

greatly enrich the bass sound.

has better electronics, higher

SIN

ratio and is more linear than

any source unit volume available. If engine noise is audible, try

raising the volume on the source unit, and/or check the ground

connection on the unit.
